Chimney Chase Cover / Chimney Caps
A vital element of a working chimney is a chimney chase cover. A chimney chase cover is the fixture that fits over the top of a framed chimney chase to keep the weather, critters and debris out. This protective piece fits over the top of your chimney similar to the lid on a shoe box. It is very important to have a chase cover in good condition because a malfunctioning or deteriorating chase cover could result in severe problems for the interior of the chimney chase.
Galvanized chase covers will last about 8 to 10 years. Near the end of their life, the condition of your chase cover can cause serious damage . The rusting of the galvanized top will discolor the sides of the chimney chase. With the rust also comes the deterioration of the cover itself. This often leads to the middle of the cover sinking a bit and accumulating water, leaves and other debris. The rust and additional stress on this cover causes the top to weaken. Cracks and holes can develop that allows for water to seep into the structure. This can cause damage such as rotting any wood framing, severe rusting and deterioration in the firebox, carbon monoxide leakage, mold, and other structural damages including damage to the sheet rock and finishing materials.
If you have a zero clearance fireplace with a pre-fabricated chimney, it may have come with galvanized chase cover. These covers can rust quickly. Don't wait to replace these protective covers that if deteriorated can result in serious damage to your chimney system.
Chase covers are made from various metals, each with varying degrees of durability. Galvanized, stainless steel and even copper are the materials of choice.
Chimney caps to cover the flue opening at the top of the chimney are also a key component of your chimney system to protect against debris and water from entering the top of the chimney. They also prevent small animals and birds from making a home in your chimney!
